Arthrodesis of flail or partially flail wrists using a dynamic compression plate without bone grafting.

Between June 1991 and May 1996 we carried out arthrodesis on 15 patients with flail or partially flail wrists using an AO/ASIF dynamic compression plate (DCP) without a bone graft. The wrist was approached through the second extensor compartment. The minimum follow-up was for 24 months with a mean of 34.2 months. All 15 wrists fused without major complications at a mean of 11.9 weeks. Stabilisation improved the function of the hand affected with paralysis and the appearance of the extensively paralysed upper limb with a flail hand. In the absence of bony abnormality fusion can be obtained with a DCP alone without the need for bone grafting.
